It is indispensable when the length\/diameter ratio of the workpiece exceeds 4:1 (for a fixed steady rest) or 10:1 (for a traveling steady rest that accompanies the tool). Without a steady rest, long workpieces flex under cutting force, producing taper, vibrations, and non-cylindrical surfaces.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between a fixed steady rest and a traveling (rotary) steady rest?\u003c\/summary\u003e\n\u003cp\u003eA fixed steady rest is locked onto the bed in a fixed position and supports the workpiece at a specific point. A traveling steady rest (or follower rest) is fixed on the longitudinal carriage and accompanies the tool during movement — it supports the workpiece always at the same point relative to the tool, eliminating deflection during feeding. A traveling steady rest is necessary for turning very long workpieces where a fixed steady rest is not sufficient.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this steady rest compatible with my Bernardo lathe?\u003c\/summary\u003e\n\u003cp\u003eEach Bernardo steady rest is designed for the models indicated in the title. The workpiece diameter range (e.g., 50–590 mm) indicates the supportable workpieces. Check that your lathe model matches the one indicated.

Lubricate the jaws with cutting oil or grease to reduce wear. Do not tighten the jaws forcefully — they must support the workpiece without clamping it.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDelivery times?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 business days shipping.
